DESCRIPTION This relay module is suited for switching on or off the lighting in the living room, the garden fountain, the mains outlets in the children’s room, and many more. In order to limit the wiring in the switchboard cabinet, this module features a mains voltage input and four voltage outputs to which the consumer can be connected directly. This is only suited for use in a Velbus system. Multiple functions, e.g. switching on/off timers, are to be programmed via the Velbuslink software.
• multiple control functions o moment o off o on o on/off o timer (start/stop, restartable or non-restartable, switch-on/off delay, interval) o output forced off o output forced on o output inhibition o etc.
VELBUS CHARACTERISTICS • • • • • • 2-wire communication for Velbus data and 2 wires for power data transfer: 16.6 kbit/s serial data protocol: CAN (Controller Area Network) short-circuit proof (towards (-) or (+) of power) bus error indication: 2 short blinks of the operation mode LED self-restoring after 25 seconds in case of a bus error Possibility to assign a name (max. 16 characters) to each output channel.

LOCAL CONTROL Remove the cover.
USE Connecting a 230V mains voltage to the input allows you to switch 4 mains voltage consumers like lighting, a pump, an electric heater, electric valves, etc. Connecting a 12V low voltage to the input allows you to switch 4 low-voltage consumers like low-voltage lighting, LED strips, low-voltage LED spots, etc.
A double-pole load (e.g. mains outlet) requires an extra double-pole relay. A triple-pole load (e.g. water heater) requires a quadrupole relay.
Low-Voltage Connection Diagram The module is also suitable for controlling 12V or 24V LED bulbs or strips. The input will then be connected to a low-voltage power supply (12V or 24V). Choose a power supply which can deliver the required consumption while the total consumption does not exceed 12A.
Termination Remove the cover. Termination Generally, only 2 ‘TERM’ terminators must be used in a complete Velbus® installation. Usually, this will be on one module inside the distribution box and on the module which is physically located furthest from the distribution box. On all other modules, the terminator must be removed.
Configuration This relay module can only be configured through the Velbuslink software. The address, behaviour and control functions can be configured manually. Address Each module in the Velbus connection must have a unique address. Configure the address through the software. Relay Contact Behaviour The relay contact will behave as an NO contact (no voltage on the outputs at no load).
11 Toggle with timers disabled Each press toggles the relay status (on/off). The timers cannot be started when the relay is switched on. A PIR detector will switch on the driveway lighting; this lighting can switched on/off with a pushbutton. A driveway lighting switched on through the pushbutton will not be affected by the PIR detector. 12 Toggle with timers disabled at short press Each press toggles the relay status (on/off).
24 Restartable interval timer Pressing the pushbutton will switch on the interval timer for a preset time. The output is thus repeatedly open and closed. The switch-on and switch-off delays can be set. Pressing the pushbutton while the interval timer is running will restart the interval timer. 25 Non restartable interval timer Pressing the pushbutton will switch on the interval timer for a preset time. The output is thus repeatedly open and closed. The switch-on and switch-off delays can be set.
40 Cancel inhibit at pushbutton press Pressing the pushbutton will transfer the internal status to the relay. A light sensor will switch on the garden lighting at dusk. A pushbutton on the control panel will inhibit the output at 23h00; a second pushbutton will cancel this inhibition at 06h00 via the weekly program. This will keep the garden lighting switched off between 23h00 and 06h00.
CHECKING THE SOFTWARE VERSION The software version can be verified via the Velbus link software. Check on http://www.velbus.eu whether you have the latest version. If a newer version is available, download it. Connect the Velbus interface to a PC and run the upgrade-software and follow the instructions on the screen. Remark: Upgrading a module is not without risk. Do not interrupt the process! If for any reason the upgrade should fail, the module will cease normal operation.
